5. Covenants

A. Agreements of the Enbridge Entities. Each of the Enbridge Entities and, except with respect to paragraphs (g), (h), (i), (j) and (p) of this Section 5A, Enbridge, agrees with the several Underwriters as follows:

Entities and Enbridge will endeavor to cause the Registration Statement, such post-effective amendment or such new registration statement to become effective as soon as possible and will advise you and counsel for the Underwriters promptly and, if requested by you, will confirm such advice in writing, when the Registration Statement, such post-effective amendment or such new registration statement has become effective.

(b) Following the execution and delivery of this Agreement and thereafter from time to time during such period as in the opinion of counsel for the Underwriters a prospectus is required by the Act to be delivered in connection with sales by the Underwriters or any dealer (the “Prospectus Delivery Period”), each of the Enbridge Entities and Enbridge will advise you and counsel for the Underwriters promptly and, if requested by you, will confirm such advice in writing: (i) of any request by the Commission for amendment of or a supplement to the Registration Statement, the Pricing Disclosure Package or the Final Prospectus or for additional information; (ii) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or preventing or suspending the use of the Pricing Disclosure Package, the Final Prospectus or any Issuer Free Writing Prospectus or of any examination by the Commission pursuant to Section 8(e) of the Act concerning the Registration Statement of which either of the Enbridge Entities or Enbridge is aware or of the suspension of qualification of the Offered Shares, the Purchase Obligation, the corresponding i-units or the Partnership’s Class A Common Units for offering and sale in any jurisdiction or the initiation of any proceeding for such purpose; (iii) if either of the Enbridge Entities or Enbridge receives notice that it has become the subject of a proceeding under Section 8A of the Act in connection with the offering of the Offered Shares; and (iv) of any change in the financial position, business, prospects, or results of operations of any of the Companies or of Enbridge, or of the happening of any event, that makes any statement of a material fact made in the Registration Statement, the Pricing Disclosure Package or the Final Prospectus (as then amended or supplemented) untrue or that requires the making of any additions to or changes in the Registration Statement, the Pricing Disclosure Package or the Final Prospectus (as then amended or supplemented) in order to state a material fact required by the Act to be stated therein or necessary in order to make the statements therein (in the case of the Pricing Disclosure Package and the Final Prospectus, in the light of the circumstances under which they were made), not misleading, or of the necessity to amend or supplement the Registration Statement, the Pricing Disclosure Package or the Final Prospectus (as then amended or supplemented) to comply with the Act or any other law. If at any time within the Prospectus Delivery Period, the Commission shall issue any stop order suspending the effectiveness of the Registration Statement or preventing or suspending the use of the Pricing Disclosure Package, the Final Prospectus or any Issuer Free Writing Prospectus, each of the Enbridge Entities and/or Enbridge, as applicable, will make every reasonable effort to obtain the withdrawal of such order at the earliest possible time.

(c) Each of the Enbridge Entities and Enbridge will furnish to you, at your request and without charge, (i) one conformed copy of the Registration Statement as originally filed with the Commission and of each amendment thereto, including financial statements and all exhibits to the Registration Statement, (ii) such number of conformed copies of the Registration Statement as originally filed and of each amendment thereto, but without exhibits, as you may request, (iii) such number of copies of the Incorporated Documents, without exhibits, as you may request, (iv) such number of copies of the exhibits to the Incorporated Documents and the Pricing Disclosure Package as you may request, and (v) such number of copies of the

Preliminary Prospectus, the Final Prospectus, any amended or supplemented Final Prospectus and each Issuer Free Writing Prospectus as you may request.

(d) During the Prospectus Delivery Period, neither of the Enbridge Entities nor Enbridge will file any amendment to the Registration Statement or make any amendment or supplement to the Final Prospectus or file any document that, upon filing becomes an Incorporated Document, of which you and counsel for the Underwriters shall not previously have been advised or to which, after you and counsel for the Underwriters shall have received a copy of the document proposed to be filed, you shall reasonably object; provided that your consent shall not be unreasonably withheld or delayed.

(e) Neither of the Enbridge Entities nor Enbridge will make any offer relating to the Offered Shares that would constitute an Issuer Free Writing Prospectus without the prior written consent of Credit Suisse Securities (USA) LLC, ▇▇▇▇▇▇▇ Lynch, Pierce, ▇▇▇▇▇▇ & ▇▇▇▇▇ Incorporated, Barclays Capital Inc. and ▇▇▇▇▇▇▇, Sachs & Co. (collectively, the “Representatives”). Each of the Enbridge Entities and Enbridge will retain in accordance with the Act all Issuer Free Writing Prospectuses not required to be filed pursuant to the Act; and if at any time after the date hereof through the completion of the offering of the Offered Shares any events shall have occurred as a result of which any Issuer Free Writing Prospectus, as then amended or supplemented, would conflict with the information in the Registration Statement, the Pricing Disclosure Package or the Final Prospectus or would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or, if for any other reason it shall be necessary to amend or supplement any Issuer Free Writing Prospectus, to notify the Representatives and, upon your request, to file such documents and to prepare and furnish without charge to the Underwriters as many copies as you may from time to time reasonably request of an amended or supplemented Issuer Free Writing Prospectus, that will correct such conflict, statement or omission or effect such compliance.

(f) Each of the Enbridge Entities and Enbridge will cause the Final Prospectus to be filed pursuant to, and in compliance with, Rule 424(b). The Enbridge Entities will pay to the Commission the registration fee associated with the offering of the Offered Shares and the corresponding i-units within the time period required by Rule 456(b)(i) under the Act and otherwise in accordance with Rules 456(b) and 457(r) under the Act. As soon as practical following the execution and delivery of this Agreement and until the end of the Prospectus Delivery Period, the Enbridge Entities will expeditiously deliver to the Underwriters and each dealer, without charge, as many copies of the Final Prospectus (and of any amendment or supplement thereto) as you may reasonably request. Each of the Enbridge Entities and Enbridge consent to the use of the Final Prospectus (and of any amendment or supplement thereto) in accordance with the provisions of the Act and with the securities or Blue Sky laws of the jurisdictions in which the Offered Shares are offered by the Underwriters and by all dealers to whom Offered Shares may be sold, both in connection with the offering and sale of the Offered Shares and for such period of time thereafter as the Final Prospectus is required by the Act to be delivered in connection with sales by the Underwriters or any dealer. If during such period of time any event shall occur that in the judgment of the Enbridge Entities or Enbridge or in the opinion of counsel for the Underwriters is required to be set forth in the Final Prospectus (as then amended or supplemented) or should be set forth therein in order to make the statements therein,

in the light of the circumstances under which they were made, not misleading, or if it is necessary to supplement or amend the Final Prospectus (or to file under the Exchange Act any document that, upon filing, becomes an Incorporated Document) in order to comply with the Act or any other law, the Enbridge Entities or Enbridge, as applicable, will forthwith prepare and, subject to the provisions of paragraph (d) above, file with the Commission an appropriate supplement or amendment thereto (or to such document), and will expeditiously furnish to the Underwriters and dealers a reasonable number of copies thereof. In the event that the Enbridge Entities, Enbridge and the Underwriters agree that the Final Prospectus should be amended or supplemented, the Enbridge Entities or Enbridge, as applicable, if requested by you, will promptly issue a press release announcing or disclosing the matters to be covered by the proposed amendment or supplement.

(g) Each of the Enbridge Entities will cooperate with you and with counsel for the Underwriters in connection with the registration or qualification of the Offered Shares for offering and sale by the Underwriters and by dealers under the securities or Blue Sky laws of such jurisdictions as you may designate and will file such consents to service of process or other documents necessary or appropriate in order to effect such registration or qualification; provided that in no event shall either of the Enbridge Entities be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering and sale of the Offered Shares, in any jurisdiction where it is not now so subject.

(h) The Enbridge Entities will make generally available to security holders of the Company a consolidated earnings statement, which need not be audited, covering a 12-month period commencing after the effective date of the Registration Statement and ending not later than 15 months thereafter, as soon as practicable after the end of such period, which consolidated earnings statement shall satisfy the provisions of Section 11(a) of the Act.

(i) If this Agreement shall terminate or shall be terminated after execution pursuant to any provisions hereof (otherwise than pursuant to Section 10 hereof or pursuant to clause (ii), (iii), (iv) or (v) of Section 12 hereof) or if this Agreement shall be terminated by the Underwriters because of any failure or refusal on the part of either of the Enbridge Entities or Enbridge to comply with the terms or fulfill any of the conditions of this Agreement, the Company agrees to reimburse the Underwriters for all out-of-pocket expenses (including reasonable fees and expenses of counsel for the Underwriters) incurred by the Underwriters in connection herewith.

(j) The Enbridge Entities will apply the net proceeds from the sale of the Offered Shares substantially in accordance with the description set forth in the Final Prospectus, and the Partnership shall duly authorize and issue i-units to the Company as contemplated in the Final Prospectus.

(k) Except as provided in this Agreement, none of the Companies nor Enbridge will offer, sell, contract to sell or otherwise dispose of or hedge any Securities or any securities of the Company or of the Partnership substantially similar to, convertible into or exercisable or exchangeable for Securities, or grant any options or warrants to purchase any Securities or any such securities, for a period of 45 days after the date of the Final Prospectus,

without the prior written consent of the Representatives; provided, however, the foregoing restriction shall not apply to (i) an automatic increase in the number of i-units outstanding and owned by the Company, or (ii) the distribution of additional shares representing limited liability company interests in the Company to the owners of Company shares, upon the occurrence of a regular quarterly cash distribution by the Partnership on its Class A Common Units and Class B Common Units.

(l) Except as stated in this Agreement and in the Final Prospectus, none of the Companies nor Enbridge has taken, nor will any of the Companies take, directly or indirectly, any action designed to or that might reasonably be expected to cause or result in stabilization or manipulation of the price of any securities of either of the Enbridge Entities to facilitate the sale or resale of the Offered Shares.

(m) Each of the Enbridge Entities and Enbridge, during the Prospectus Delivery Period, will file all documents required to be filed with the Commission pursuant to the Exchange Act within the time periods required by the Exchange Act.

(n) Each of the Enbridge Entities and Enbridge hereby acknowledges that the Underwriters are acting solely as underwriters in connection with the purchase and sale of the Offered Shares. Each of the Enbridge Entities and Enbridge further acknowledges that the Underwriters are acting pursuant to a contractual relationship created solely by this Agreement entered into on an arm’s length basis and in no event do the parties intend that the Underwriters act or be responsible as a fiduciary to any of the Companies or Enbridge, their management, stockholders, creditors or any other person in connection with any activity that the Underwriters may undertake or have undertaken in furtherance of the purchase and sale of the Offered Shares, either before or after the date hereof. The Underwriters hereby expressly disclaim any fiduciary or similar obligations to any of the Companies or Enbridge, either in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions, and each of the Enbridge Entities and Enbridge hereby confirms its understanding and agreement to that effect. The Enbridge Entities, Enbridge and the Underwriters agree that they are each responsible for making their own independent judgments with respect to any such transactions and that any opinions or views expressed by the Underwriters to any of the Companies or Enbridge regarding such transactions, including but not limited to any opinions or views with respect to the price or market for the Offered Shares, do not constitute advice or recommendations to any of the Companies or Enbridge. Each of the Enbridge Entities and Enbridge hereby waives and releases, to the fullest extent permitted by law, any claims that it may have against the Underwriters with respect to any breach or alleged breach of any fiduciary or similar duty to any of the Companies or Enbridge in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions.

(o) Each of the Enbridge Entities and Enbridge hereby acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold and make statements or investment recommendations and/or publish research reports with respect to the Enbridge Entities, Enbridge and/or the offering of the Offered Shares that differ from the views of its investment bankers. Each of the Enbridge Entities and Enbridge acknowledges that each of the

Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of one or more of the Companies or Enbridge that may be the subject of the transactions contemplated by this Agreement.

(p) The Company will use its best efforts to have the Offered Shares listed, subject to official notice of issuance, on the NYSE on or before the Closing Date.

(q) Upon completion of the offering of the Offered Shares and the issuance of the corresponding i-units by the Partnership, the General Partner shall make the additional capital contributions to the Partnership as required by Section 4.4(c) of the Fourth Amended and Restated Agreement of Limited Partnership of the Partnership, dated as of August 15, 2006, as amended to date.

B. Agreement of the Underwriters. Each Underwriter, severally and not jointly agrees that, without the prior written consent of the Company and the Representatives, it has not made and will not make any offer relating to the Shares that would constitute a “free writing prospectus” as defined in Rule 405 under the Act that is required to be filed with the Commission.

6. Representations and Warranties of the Enbridge Entities.

A. Each of the Enbridge Entities, jointly and severally, represents and warrants (provided that no representation and/or warranty is hereby being made as to Enbridge, the Purchase Obligation or any of the Enbridge Information (as hereinafter defined)) to each Underwriter that:

(a) The Registration Statement conformed and will conform in all material respects on the most recent Effective Date and on the applicable Closing Date, and any amendment to the Registration Statement filed after the date hereof will conform in all material respects when filed, to the requirements of the Act. The Pricing Disclosure Package conformed, and the Final Prospectus will conform, in all material respects when filed with the Commission pursuant to Rule 424(b) and on the applicable Closing Date to the requirements of the Act. The Registration Statement did not, as of the most recent Effective Date, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and the statements made or to be made in such document that are covered by Rule 175(b) under the Act were made or will be made with a reasonable basis and in good faith; provided that no representation or warranty is made as to information contained in or omitted from such document in reliance upon and in conformity with written information furnished to the Enbridge Entities through the Underwriters specifically for inclusion therein, which information is specified in Section 13 hereof. The Final Prospectus will not, as of its date and on the applicable Closing Date, include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that no representation or warranty is made as to information included in or omitted from the Final Prospectus in reliance upon and in

conformity with written information furnished to the Enbridge Entities through the Underwriters specifically for inclusion therein, which information is specified in Section 13 hereof.

(b) The Incorporated Documents (other than those filed by Enbridge) heretofore filed, when they were filed (or, if any amendment with respect to any such document was filed, when such amendment was filed), conformed in all material respects with the requirements of the Exchange Act; any further Incorporated Documents (other than those filed by Enbridge) so filed will, when they are filed, conform in all material respects with the requirements of the Exchange Act; no Incorporated Document (other than those filed by Enbridge) when it was filed (or, if an amendment with respect to any such document was filed, when such amendment was filed), included an untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and no such further document, when it is filed, will include an untrue statement of a material fact or will omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(c) The Pricing Disclosure Package did not, as of the Applicable Time, include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that no representation or warranty is made as to information included in or omitted from the Pricing Disclosure Package in reliance upon and in conformity with written information furnished to the Enbridge Entities through the Underwriters specifically for inclusion therein, which information is specified in Section 13 hereof.

(d) Each Issuer Free Writing Prospectus (including, without limitation, any road show that is a free writing prospectus under Rule 433), when considered together with the Pricing Disclosure Package as of the Applicable Time, did not contain an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. Each Issuer Free Writing Prospectus, as of its date and at all subsequent times through the completion of the offering of the Offered Shares, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement, the Pricing Disclosure Package or the Final Prospectus.

(e) Each Issuer Free Writing Prospectus conformed or will conform in all material respects to the requirements of the Act on the date of first use, and the Company has complied with any filing requirements applicable to such Issuer Free Writing Prospectus pursuant to the Act. Neither of the Enbridge Entities has made any offer relating to the Offered Shares that would constitute an Issuer Free Writing Prospectus without the prior written consent of the Representatives. The Enbridge Entities have retained in accordance with the Act all Issuer Free Writing Prospectuses that were not required to be filed pursuant to the Act.

(f) Each of the Enbridge Entities has been at all times since the initial filing of the EEQ/EEP Registration Statement and continues to be a “well-known seasoned issuer” (as defined in Rule 405 under the Act) eligible to use an “automatic shelf registration statement” (as defined in Rule 405 under the Act) for the registration of the Offered Shares, and has not been an “ineligible issuer” (as defined in Rule 405 under the Act) with respect to firm commitment underwritings at any time since such date. Neither of the Enbridge Entities has received from the Commission any notice pursuant to Rule 401(g)(2) under the Act objecting to the use of the form of automatic shelf registration statement (as defined in Rule 405 under the Act). To the knowledge of the Enbridge Entities, the EEQ/EEP Registration Statement is not the subject of a pending proceeding or examination under Section 8(d) or 8(e) of the Act, and neither of the Enbridge Entities is the subject of a pending proceeding under Section 8A of the Act in connection with the offering of the Offered Shares.

(g) The capitalization of the Company as at December 31, 2012 was as set forth in the Preliminary Prospectus under the heading “Capitalization”.

(h) The outstanding i-units in the Partnership have been duly and validly authorized and issued and are fully paid and non-assessable (except as non-assessability may be affected by the Delaware Revised Uniform Limited Partnership Act (the “Delaware Act”)) and free of any preemptive or similar rights (except for any required Capital Contributions to the Partnership to be made by the General Partner pursuant to Section 4.4(c) of the Partnership Agreement), and are owned by the Company free and clear of liens, encumbrances, security interests, charges or claims.

(i) The Shares of the Company have been duly and validly authorized and issued and are fully paid and nonassessable, except as such non-assessability may be affected by the Delaware Limited Liability Company Act (the “Delaware LLC Act”). The Offered Shares and the limited liability company interests represented thereby and the corresponding i-units have been duly and validly authorized and, when issued, delivered and paid for in accordance with Section 4 hereof (or in the case of the i-units, as set forth in the Final Prospectus), will be validly issued, fully paid and nonassessable except as non-assessability may be affected by the Delaware LLC Act or the Delaware Act, free of any preemptive or similar rights, and the Underwriters will acquire such Offered Shares free and clear of any liens, encumbrances, security interests, charges or claims.

(j) The Partnership has been duly formed and is validly existing as a limited partnership in good standing under the Delaware Act, with partnership power and authority to own or lease its properties and to conduct its business as described in the Pricing Disclosure Package and the Registration Statement. The Partnership, directly or indirectly, owns the percentage of the equity interests of each of the subsidiaries listed on Schedule IIIA hereto (the “Operating Subsidiaries”), free and clear of any lien, encumbrance, security interest, equity, charge or claim (“Lien”) except for such Liens as are not, individually or in the aggregate, material to such ownership interest or as described in the Pricing Disclosure Package and the Registration Statement.

(j) Enbridge is not and, as of the Closing Date, after giving effect to the offering and sale of the Offered Shares, will not be, an “Investment Company” as that term is defined in the Investment Company Act, or required to register as an “Investment Company” under the Investment Company Act.

(m) The interactive data in eXtensbile Business Reporting Language of Enbridge included or incorporated by reference in the Registration Statement, the Final Prospectus and the Pricing Disclosure Package fairly presents the information called for in all material respects and has been prepared in accordance with the Commission’s rules and guidelines applicable thereto at the time such interactive data was filed with the Commission.

(n) When the conditions to the Purchase Obligation are satisfied, the Purchase Obligation will be a valid and legally binding obligation of Enbridge, enforceable against Enbridge in accordance with its terms, subject to the qualification that (a) such enforceability may be limited by bankruptcy, insolvency, reorganization and other laws of general applicability relating to or affecting creditors’ rights generally, and (b) such enforceability may be limited by general equitable principles.

7. Indemnification and Contribution.

(a) The Enbridge Entities agree, jointly and severally, to indemnify and hold harmless each Underwriter and its affiliates, its and their partners, directors, officers, employees and agents and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages, liabilities and expenses (including reasonable costs of investigation) arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in the Pricing Disclosure Package, any Issuer Free Writing Prospectus , the Final Prospectus, or the Registration Statement or in any amendment or supplement thereto, other than any Enbridge Information, or arising out of or based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of the Pricing Disclosure Package and the Final Prospectus, in the light of the circumstances under which they were made), not misleading, except insofar as such losses, claims, damages,

liabilities or expenses arise out of or are based upon any untrue statement or omission or alleged untrue statement or omission that has been made therein or omitted therefrom in reliance upon and in conformity with the information relating to such Underwriter furnished in writing to the Enbridge Entities or Enbridge by or on behalf of such Underwriter expressly for use in connection therewith; provided, however, that the only information furnished in writing to the Enbridge Entities or Enbridge by or on behalf of the Underwriters are the statements noted in Section 13 hereof. The foregoing indemnity agreement shall be in addition to any liability that the Enbridge Entities may otherwise have.

(b) Enbridge agrees to indemnify and hold harmless each Underwriter and its affiliates, its and their partners, directors, officers, employees and agents and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages, liabilities and expenses (including reasonable costs of investigation) arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in the Enbridge Information in the Pricing Disclosure Package, any Issuer Free Writing Prospectus, the Final Prospectus, or the Registration Statement or in any amendment or supplement thereto, or arising out of or based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of the Pricing Disclosure Package and the Final Prospectus, in the light of the circumstances under which they were made), not misleading, except insofar as such losses, claims, damages, liabilities or expenses arise out of or are based upon any untrue statement or omission or alleged untrue statement or omission that has been made therein or omitted therefrom in reliance upon and in conformity with the information relating to such Underwriter furnished in writing to the Enbridge Entities or Enbridge by or on behalf of such Underwriter expressly for use in connection therewith; provided, however, that the only information furnished in writing to the Enbridge Entities or Enbridge by or on behalf of the Underwriters are the statements noted in Section 13 hereof. The foregoing indemnity agreement shall be in addition to any liability that Enbridge may otherwise have.

(c) If any action, suit or proceeding shall be brought against any Underwriter or any person controlling any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act in respect of which indemnity may be sought against the Enbridge Entities or Enbridge, such Underwriter or such controlling person shall promptly notify the Company on behalf of the Enbridge Entities or Enbridge, as applicable, and the Enbridge Entities or Enbridge, as applicable, shall assume the defense thereof, including the employment of counsel reasonably satisfactory to the Underwriters and payment of all fees and expenses. Such Underwriter or any such controlling person shall have the right to employ separate counsel in any such action, suit or proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Underwriter or such controlling person unless (i) the Enbridge Entities or Enbridge, as applicable, has agreed in writing to pay such fees and expenses, (ii) the Enbridge Entities or Enbridge, as applicable, have failed to assume the defense and employ counsel reasonably satisfactory to the Underwriters or (iii) the named parties to any such action, suit or proceeding (including any impleaded parties) include both such Underwriter or such controlling person and any or all of the Company, the Partnership or Enbridge, and such Underwriter or such controlling person shall have been advised by its counsel that representation of such indemnified party and any or all of the Company, the Partnership or Enbridge, as the case may be, by the same counsel would be inappropriate under

applicable standards of professional conduct (whether or not such representation by the same counsel has been proposed) due to actual or potential differing interests between them (in which case the applicable party shall not have the right to assume the defense of such action, suit or proceeding on behalf of such Underwriter or such controlling person). It is understood, however, that the Enbridge Entities and Enbridge shall, in connection with any one such action, suit or proceeding or separate but substantially similar or related actions, suits or proceedings in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of only one separate firm of attorneys (in addition to any local counsel) at any time for all such Underwriters and controlling persons not having actual or potential differing interests with you, which firm shall be designated in writing by the Representatives, and that all such fees and expenses shall be reimbursed as they are incurred. Neither of the Enbridge Entities nor Enbridge shall be liable for any settlement of any such action, suit or proceeding effected without its written consent, but if settled with such written consent, or if there be a final judgment for the plaintiff in any such action, suit or proceeding, each of the Enbridge Entities and Enbridge agrees to indemnify and hold harmless any Underwriter, to the extent provided in the applicable preceding paragraph (a) or (b), and any such controlling person from and against any loss, claim, damage, liability or expense by reason of such settlement or judgment.

(d) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless each of the Enbridge Entities and Enbridge and their respective affiliates, and their directors, officers and employees, the directors and officers of Enbridge, the General Partner and of the Company and any person who controls either of the Enbridge Entities or Enbridge within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Enbridge Entities to each Underwriter, but only with respect to information relating to such Underwriter furnished in writing by or on behalf of such Underwriter to the Enbridge Entities or to Enbridge expressly for use in the Registration Statement, the Pricing Disclosure Package or the Final Prospectus; provided, however, that the only information furnished in writing to the Enbridge Entities or to Enbridge by or on behalf of the Underwriters are the statements noted in Section 13 hereof. If any action, suit or proceeding shall be brought against any of the Company, the Partnership, any of the directors and officers of the General Partner and of the Company, or any such controlling person based on the Registration Statement, the Pricing Disclosure Package or the Final Prospectus, and in respect of which indemnity may be sought against any Underwriter pursuant to this paragraph (d), such Underwriter shall have the rights and duties given to the Enbridge Entities and Enbridge by paragraph (c) above, and the Enbridge Entities, Enbridge the directors and officers of the General Partner and of the Enbridge Entities and Enbridge, and any such controlling person, shall have the rights and duties given to the Underwriters by paragraph (c) above. The foregoing indemnity agreement shall be in addition to any liability that the Underwriters may otherwise have.

(e) If the indemnification provided for in this Section 7 is unavailable to an indemnified party under paragraphs (a), (b) or (d) hereof in respect of any losses, claims, damages, liabilities or expenses referred to therein, then an indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses (i) in such proportion as is appropriate to reflect the relative benefits received by the Enbridge Entities and Enbridge, on the one hand, and the Underwriters on the other hand, from the offering of the

Offered Shares, or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Enbridge Entities and Enbridge, on the one hand, and the Underwriters on the other hand, in connection with the statements or omissions that resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Enbridge Entities and Enbridge, on the one hand, and the Underwriters on the other hand shall be deemed to be in the same proportion as the total net proceeds from the offering of the Offered Shares (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault of the Enbridge Entities and Enbridge, on the one hand, and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Enbridge Entities or Enbridge, on the one hand, or by the Underwriters on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(f) The Enbridge Entities, Enbridge and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by a pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (e) above. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities and expenses referred to in paragraph (e) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating any claim or defending any such action, suit or proceeding. Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price of the Offered Shares underwritten by it and distributed to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 7 are several in proportion to the respective numbers of Firm Shares set forth opposite their names in Schedule I hereto (or such numbers of Firm Shares increased as set forth in Section 11 hereof) and not joint.

(g) No indemnifying party shall, without the prior written consent of the indemnified party (which consent shall not be unreasonably withheld), effect any settlement of any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes (i) an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(h) Any losses, claims, damages, liabilities or expenses for which an indemnified party is entitled to indemnification or contribution under this Section 7 shall be paid by the indemnifying party to the indemnified party as such losses, claims, damages, liabilities or

expenses are incurred. The indemnity and contribution agreements contained in this Section 7 and the representations and warranties of the Enbridge Entities and Enbridge set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter, the Enbridge Entities, the directors or officers of the General Partner and the Company, or any person controlling the Company, (ii) acceptance of any Offered Shares and payment therefor hereunder, and (iii) any termination of this Agreement. A successor to any Underwriter or any person controlling any Underwriter, or to either of the Enbridge Entities or the directors or officers of the General Partner and the Company, or any person controlling the Company, shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section 7. The term “successor,” as used in this Agreement, shall not include a purchaser from any Underwriter of any Shares in his status as a purchaser.

Such counsel shall state that the tax opinion of such counsel relating to the Offered Shares filed prior to the Closing Date as an exhibit to a Current Report on Form 8-K of the Company is confirmed and the Underwriters may rely upon such opinion as if it were addressed to them.

Such counsel shall also state that, although such counsel has not undertaken, except as otherwise indicated in their opinion, to determine independently, and does not assume any responsibility for, the accuracy or completeness of the statements in the Registration Statement, the Pricing Disclosure Package and the Final Prospectus, such counsel has reviewed and is familiar with the Registration Statement, the Pricing Disclosure Package and the Final Prospectus and such counsel has participated in conferences with officers and other representatives of the Company, Enbridge, the General Partner and the Partnership, representatives of the independent registered public accounting firm of each of the Enbridge Entities and of Enbridge and you and your representatives, at which the contents of the Registration Statement, the Pricing Disclosure Package and the Final Prospectus and related matters (including review and discussion of the contents of all Incorporated Documents) were

discussed, and no facts have come to such counsel’s attention that lead such counsel to believe that:

(A) the Registration Statement (other than the financial statements and the notes thereto and the schedules and other financial data included therein, as to which such counsel need not express an opinion), as of its most recent Effective Date, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading,

(B) the Pricing Disclosure Package (other than the financial statements and the notes thereto and the schedules and other financial data included therein, as to which such counsel need not express an opinion), as of the Applicable Time and the Closing Date, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or

(C) the Final Prospectus (other than the financial statements and the notes thereto and the schedules and other financial data included therein, as to which such counsel need not express an opinion), as of its issue date and the Closing Date, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

In rendering such opinions, such counsel may (1) rely in respect of factual matters upon representations and warranties of the Companies and Enbridge set forth herein and certificates of officers of the Companies and Enbridge and upon information obtained from public officials, upon opinions of other counsel issued in connection with the offering of the Offered Shares and the corresponding issuance of the i-units pursuant to the Pricing Disclosure Package and the Final Prospectus and other sources believed by such counsel to be responsible, (2) assume that the certificates for the Offered Shares and for the i-units conform to the specimens thereof examined by them and have been duly countersigned by a transfer agent and duly registered by a registrar of the Shares and the i-units and that the signatures on all documents examined by such counsel are genuine, which assumptions they may state they have not independently verified, (3) state that their opinion is limited to Texas law, federal laws of the United States, the Delaware Act, the DGCL, the Delaware LLC Act and New York law, in each case exclusive of the law addressed in the legal opinions rendered by counsel referred to in clauses (e) and (f) of this Section 8, (4) state that they express no opinion with respect to state or local taxes or tax statutes to which any of the Company, the Partnership, or the Operating Subsidiaries may be subject and (5) state that their opinion is furnished as counsel for the Enbridge Entities and for Enbridge to you, and is solely for the benefit of the several Underwriters.

(e) Fraser ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇ and ▇▇▇▇▇▇, P.C., acting as special local counsel for the Enbridge Entities and the Operating Partnership with respect to the State of Michigan, shall have furnished to you, its written opinion or opinions, dated as of the Closing Date in form and substance satisfactory to you, to the effect that:

(i) Neither the offer, sale or delivery of the Offered Shares, the issuance of the corresponding i-units, the execution, delivery or performance of this Agreement, the compliance by the Enbridge Entities with the provisions hereof nor consummation by the Enbridge Entities of the transactions contemplated hereby will result in any violation of any existing Michigan law or regulation, ruling (assuming compliance with all applicable state securities and Blue Sky laws), judgment, injunction, order or decree known to such counsel after reasonable inquiry of any Michigan court or Michigan agency applicable to the Company, the Partnership, the Operating Partnership or any of their respective properties located in Michigan.

(ii) No consent, approval, authorization, order, registration or qualification of or with any Michigan governmental agency or Michigan instrumentality governing (A) oil pipelines generally or (B) the issuance of securities by entities owning oil pipelines, or, to such counsel’s knowledge, based solely upon its participation as special counsel in matters relating to the offering and sale of the Offered Shares or the issuance of the corresponding i-units pursuant to the Pricing Disclosure Package and the Final Prospectus and without in any manner having conducted an independent investigation, any other governmental agency or instrumentality of Michigan having jurisdiction over the Company, the Partnership, the Operating Partnership or any of their respective properties, is required for the offering or sale of the Offered Shares by the Company or the issuance of the corresponding i-units, except such consents, approvals, authorizations, orders, registrations or qualifications (1) as have been obtained, (2) as may be required under federal or state securities or Blue Sky laws, (3) that, if not obtained, would not, individually or in the aggregate, have a material adverse effect upon the ability of the Company, the Partnership and the Operating Partnership (taken as a whole) to conduct their respective businesses substantially in accordance with the past practice of each, or (4) as set forth or contemplated in the Pricing Disclosure Package and the Final Prospectus.

(f) You shall have received on the Closing Date an opinion of Steptoe & ▇▇▇▇▇▇▇, special FERC counsel for the Company, the Partnership and the Operating Partnership, dated the Closing Date and addressed to you, to the effect that no consent, approval, authorization, order, registration or qualification of or with the FERC with respect to the Partnership’s or the Operating Partnership’s liquids pipeline operations is required for the issuance of the Offered Shares or the corresponding i-units, the offer and sale of the Offered Shares by the Company or the execution, delivery and performance of this Agreement.

(iv) All necessary corporate action has been taken by Enbridge to authorize the execution and delivery of this Agreement; this Agreement has been duly executed by Enbridge in accordance with the laws of the Province of Alberta and the federal laws of Canada applicable therein; and Enbridge has all necessary corporate power and authority to consummate the transactions contemplated by this Agreement.

(v) Neither the execution, delivery or performance of this Agreement by Enbridge or compliance by Enbridge with the provisions hereof, nor consummation by Enbridge of the transactions contemplated hereby will (i) result in a breach or violation of any of the terms or provisions of, or constitute a default under, any of the documents listed as Exhibit A¹ to such opinion, (ii) result in any violation of the provisions of the Certificate of Incorporation or Bylaws of Enbridge, (iii) breach or otherwise violate an existing obligation of Enbridge under any existing court or administrative order, judgment or decree of which such counsel has knowledge, or (iv) violate any applicable provisions of the laws of the Province of Alberta or the federal laws of Canada applicable thereto.

(vi) No consent, approval, registration, qualification, authorization or order, or filing with, any governmental agency or other governmental instrumentality of Canada or the province of Alberta is required for the performance by Enbridge of its obligations under this Agreement; except in each case as would not reasonably be expected, individually or in the aggregate, to have a material adverse effect on the financial position, results of operations, business or prospects of Enbridge and its subsidiaries, taken as a whole.

(j) No stop order suspending the effectiveness of the Registration Statement or preventing or suspending the use of the Pricing Disclosure Package, the Final Prospectus or any Issuer Free Writing Prospectus shall have been issued and no proceedings for that purpose shall have been taken or, to the knowledge of any of the Companies or Enbridge, shall be threatened by the Commission at or prior to the Closing Date; (ii) there shall not have been any change in the capitalization of the Company, the Partnership or Enbridge nor any material increase in the short-term or long-term debt of the Company, the Partnership or Enbridge (other than in the ordinary course of business) from that set forth or contemplated in the Registration Statement or the Pricing Disclosure Package; (iii) none of the Companies shall have any liabilities or obligations, direct or contingent (whether or not in the ordinary course of business), that are material to the General Partner, the Partnership, the Company and the Operating Subsidiaries (taken as a whole), other than those reflected in the Registration Statement or the Pricing Disclosure Package; and (iv) all the representations and warranties of the Enbridge Entities and Enbridge contained in this Agreement shall be true and correct on and as of the date hereof and on and as of the Closing Date as if made on and as of the Closing Date, and you shall have received a certificate, dated the Closing Date and signed by the chief executive officer and the chief financial officer (or such other officers as are acceptable to you) of the Company and Enbridge, to the effect set forth in this Section 8(j) and in Section 8(k) hereof and with respect to the foreign qualifications of the Companies and the Material Subsidiaries.

(k) Neither of the Enbridge Entities nor Enbridge shall have failed at or prior to the Closing Date to have performed or complied with any of its agreements herein contained and required to be performed or complied with by it hereunder at or prior to the Closing Date.

(l) Prior to the Closing Date, the Offered Shares shall have been listed, subject only to official notice of issuance, on the NYSE.

(m) Each of the Company, the Partnership and the General Partner shall have furnished or caused to be furnished to you such further certificates and documents as you shall have reasonably requested that are customary in closing transactions of the nature contemplated by this Agreement.

All such opinions, certificates, letters and other documents will be in compliance with the provisions hereof only if they are satisfactory in form and substance to you and counsel for the Underwriters.

Any certificate or document signed by any officer of Enbridge, the General Partner or of the Company, whether on behalf of itself or the Partnership, and delivered to you or to counsel for the Underwriters, shall be deemed a representation and warranty by Enbridge, the Company or Partnership, as the case may be, to the Underwriters as to the statements made therein.

The several obligations of the Underwriters to purchase Additional Shares hereunder are subject to the satisfaction on and as of any Option Closing Date of the conditions set forth in this Section 8, except that, the opinions, letters and certificates called for by paragraphs (c) through (i) and (m) shall be revised to reflect the sale of Additional Shares and, if any Option Closing Date is other than the Closing Date, dated the Option Closing Date in question.

9. Expenses. The Enbridge Entities agree, jointly and severally, to pay the following costs and expenses and all other costs and expenses incident to the performance by them of their obligations hereunder: (i) the preparation, printing or reproduction, and filing with the Commission of the Registration Statement (including financial statements and exhibits thereto), the Final Prospectus, the Pricing Disclosure Package, each amendment or supplement to any of them; (ii) the printing (or reproduction) and delivery (including postage, air freight charges, charges for counting and packaging and charges relating to electronic delivery) of such copies of the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, the Final Prospectus, the Incorporated Documents, and all amendments or supplements to any of them, as may be reasonably requested for use in connection with the offering and sale of the Offered Shares; (iii) the preparation, printing, authentication, issuance and delivery of the Offered Shares and the corresponding i-units; (iv) the printing (or reproduction) and delivery of this Agreement, any preliminary or supplemental Blue Sky Memoranda and all other agreements or documents printed (or reproduced) and delivered in connection with the offering of the Offered Shares; (v) the listing of the Offered Shares on the NYSE; (vi) the registration or qualification of the Offered Shares for offering and sale under the securities or Blue Sky laws of the several states as provided in Section 5A(g) hereof, if required (including the reasonable fees, expenses and disbursements of counsel for the Underwriters relating to the preparation, printing or reproduction, and delivery of any preliminary or supplemental Blue Sky Memoranda and such registration and qualification); (vii) the filing fees and the fees and expenses of counsel for the Underwriters in connection with any filings required to be made with FINRA; (viii) the transportation and lodging expenses incurred by or on behalf of representatives of the Enbridge Entities in connection with any presentations to prospective purchasers of the Offered Shares; (ix) the fees and expenses of the accountants for the Companies and Enbridge; (x) the fees and expenses of counsel for the Companies and Enbridge; and (xi) any fees payable to DTC in connection with the Offered Shares being book-entry only securities.

10. Effective Date of Agreement. This Agreement shall become effective: (i) upon the execution and delivery hereof by the parties hereto; or (ii) if, at the time this Agreement is executed and delivered, it is necessary for the Registration Statement or a post-effective amendment thereto to be declared effective before the offering of the Offered Shares may commence, when notification of the effectiveness of the Registration Statement or such post-effective amendment has been given by the Commission. Until such time as this Agreement shall have become effective, it may be terminated by the Enbridge Entities or Enbridge by notifying the Representatives, or by the Representatives by notifying the Enbridge Entities and Enbridge.

11. Non-Defaulting Underwriters. If any one or more of the Underwriters shall fail or refuse to purchase Offered Shares that it or they are obligated to purchase hereunder on the Closing Date, and the aggregate number of Offered Shares that such defaulting Underwriter or Underwriters are obligated but fail or refuse to purchase is not more than one tenth of the aggregate number of the Offered Shares which the Underwriters are obligated to purchase on the Closing Date, each non-defaulting Underwriter

shall be obligated, severally, in the proportion that the number of Firm Shares set forth opposite its name in Schedule I hereto bears to the aggregate number of Firm Shares set forth opposite the names of all non-defaulting Underwriters or in such other proportion as you may specify in accordance with the Master Agreement Among Underwriters relating to the offering of the Offered Shares, to purchase the Offered Shares that such defaulting Underwriter or Underwriters are obligated, but fail or refuse, to purchase. If any one or more of the Underwriters shall fail or refuse to purchase Offered Shares that it or they are obligated to purchase on the Closing Date and the aggregate number of Offered Shares with respect to which such default occurs is more than one tenth of the aggregate number of Offered Shares that the Underwriters are obligated to purchase on the Closing Date and arrangements satisfactory to you and the Enbridge Entities for the purchase of such Offered Shares by one or more non-defaulting Underwriters or other party or parties approved by you and the Enbridge Entities are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any party hereto (other than the defaulting Underwriter). In any such case that does not result in termination of this Agreement, either you or the Enbridge Entities shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement and the Prospectus or any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any such default of any such Underwriter under this Agreement. The term “Underwriter” as used in this Agreement includes, for all purposes of this Agreement, any party not listed in Schedule I hereto who, with your approval and the approval of the Enbridge Entities, purchases Offered Shares that a defaulting Underwriter is obligated, but fails or refuses, to purchase.

Any notice under Section 10 or this Section 11 may be made by telegram, telecopy or telephone but shall be subsequently confirmed by letter.

12. Termination of Agreement. This Agreement shall be subject to termination in the Representatives’ absolute discretion, without liability on the part of any Underwriter to either of the Enbridge Entities or to Enbridge if at or prior to the Closing Date or any Option Closing Date (if different from the Closing Date and then only as to the Additional Shares), as the case may be; (i) there has been, since the Applicable Time, the time of execution of this Agreement or since the respective dates as of which information is given in the Pricing Disclosure Package and the Final Prospectus, any material adverse change in the financial position, results of operations, business or prospects of the Partnership, the Company and the Operating Subsidiaries (taken as a whole), whether or not arising in the ordinary course of business; (ii) trading in the Class A Common Units of the Partnership or the Shares in the Company shall be suspended or subject to any restriction or limitation not in effect on the date of this Agreement; (iii) trading in securities generally on the NYSE, the NYSE Amex Equities or The Nasdaq Stock Market shall have been suspended or materially limited; (iv) a general moratorium on commercial banking activities in New York shall have been declared by either federal or state authorities or there shall have been a material disruption in commercial banking or securities settlement or clearance services in the United States; or (v) there shall have occurred any material adverse change in the financial markets in the United States or Canada, any outbreak or escalation of hostilities or the declaration by the United States of a national emergency or war or other international or domestic calamity, crisis

or change in political, financial or economic conditions, the effect of which on the financial markets of the United States is such as to make it, in the Representatives’ judgment, impracticable or inadvisable to commence or continue the offering or delivery of the Offered Shares on the terms and in the manner contemplated by the Registration Statement, the Pricing Disclosure Package and as set forth on the cover page of the Final Prospectus or to enforce contracts for the resale of the Offered Shares by the Underwriters. Notice of such termination shall be promptly given to the Company and to Enbridge by telecopy or telephone and shall be subsequently confirmed by letter.

13. Information Furnished by the Underwriters. The statements set forth in the last paragraph on the cover page and the statements in the (i) fifth, eighth, eleventh and twelfth paragraphs under the caption “Underwriting” in each of the Preliminary Prospectus and the Final Prospectus, in each of the Preliminary Prospectus and the Final Prospectus, constitute the only information furnished by or on behalf of the Underwriters as such information is referred to in Sections 6(a), 6(c) and 7 hereof.

14. Notice. Except as otherwise provided in Sections 5, 10, 11 and 12 hereof, notice given pursuant to any provision of this Agreement shall be in writing and shall be delivered (i) if to the Company or the Partnership, at the office of the General Partner, at ▇▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇, Attention: E. ▇▇▇▇▇ ▇▇▇▇▇▇▇, Assistant Secretary; or (ii) if to the Underwriters, Credit Suisse Securities (USA) LLC, ▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇-▇▇▇▇, Attention: LCD-IBD; ▇▇▇▇▇▇▇ Lynch, Pierce, ▇▇▇▇▇▇ & ▇▇▇▇▇ Incorporated, ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, Attention: Syndicate Department, with a copy to ECM Legal; Barclays Capital Inc., Attention: Syndicate Registration, ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇ (fax: ▇▇▇-▇▇▇-▇▇▇▇; and ▇▇▇▇▇▇▇, ▇▇▇▇▇ & Co., ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, Attention: Registration Department.

15. Parties. This Agreement has been and is made solely for the benefit of the several Underwriters, the Enbridge Entities, the directors and officers of the General Partner and the Company, and the other controlling persons referred to in Section 7 hereof and their respective successors and assigns, to the extent provided herein, and no other person shall acquire or have any right under or by virtue of this Agreement. Neither the term “successor” nor the term “successors and assigns” as used in this Agreement shall include a purchaser from any Underwriter of any of the Offered Shares in his status as such purchaser.

16. Applicable Law. This Agreement and any claim, controversy or dispute relating to or arising out of this Agreement shall be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.

17. Counterparts.

This Agreement may be signed in various counterparts, which together constitute one and the same instrument. If signed in counterparts, this Agreement shall not become effective unless at least one counterpart hereof shall have been executed and delivered on behalf of each party hereto.

18. Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company, the Partnership and the Underwriters, or any of them, with respect to the subject matter hereof.

19. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates of officers of Enbridge, the General Partner and the Company submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or controlling person, or by or on behalf of Enbridge or the Companies, and shall survive delivery of the Offered Shares to the Underwriters.

20. Submission to Jurisdiction. Except as set forth below, no claim may be commenced, prosecuted or continued in any court other than the courts of the State of New York located in the City and County of New York or in the United States District Court for the Southern District of New York, which courts shall have jurisdiction over the adjudication of such matters, and each of Enbridge and the Enbridge Entities consents to the jurisdiction of such courts and personal service with respect thereto. Each of Enbridge and the Enbridge Entities hereby consents to personal jurisdiction, service and venue in any court in which any claim arising out of or in any way relating to this Agreement is brought by any third party against any Underwriter or any indemnified party. Each of the Underwriters, Enbridge and the Enbridge Entities (on their own behalf and, to the extent permitted by applicable law, on behalf of their equityholders and affiliates) waives all right to trial by jury in any action, proceeding or counterclaim (whether

based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement. Each of Enbridge and the Enbridge Entities agrees that a final judgment in any such action, proceeding or counterclaim brought in any such court shall be conclusive and binding upon Enbridge or such Enbridge Entity, and may be enforced in any other courts to the jurisdiction of which Enbridge, the Company or the Partnership is or may be subject, by suit upon such judgment.

21. Judgment Currency. In respect of any judgment or order given or made for any amount due hereunder by Enbridge that is expressed and paid in a currency (the “judgment currency”) other than United States dollars, including any obligation by Enbridge as an indemnifying party under Section 7(b), Enbridge will indemnify each Underwriter against any loss incurred by such Underwriter as a result of any variation as between (i) the rate of exchange at which the United States dollar amount is converted into the judgment currency for the purpose of such judgment or order and (ii) the rate of exchange at which an Underwriter is able to purchase United States dollars with the amount of the judgment currency actually received by such Underwriter. The foregoing

indemnity shall constitute a separate and independent obligation of Enbridge and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term “rate of exchange” shall include any premiums and costs of exchange payable in connection with the purchase of or conversion into United States dollars.

22. Patriot Act. In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Enbridge Entities and Enbridge, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.
